背景
laravel 5.3 以后默认开启 mysql严格模式(strict)
在mysql在严格模式下, 并且开启了ONLY_FULL_GROUP_BY的情况下,
group by 的字段没有出现在 select 的语句中会报错.关闭了严格模式就不会报错.
示例
public static function orders($phase) { return self::select(DB::raw("SUM(orders) as orders"),"type","users_id","name") ->groupBy("type","name") ->where("phase",$phase) ->get(); }
会出现如下错误，当然*号内的内容是不同的
Syntax error or access violation: 1055 '***' isn't in GROUP BY
解决方案
laravel出现上述错误是sql_mode设置导致的问题,修改config/database.php配置文件的strict => false即可关闭了严格模式:
'mysql' => [ 'driver' => 'mysql', 'host' => env('DB_HOST', 'localhost'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'forge'), 'username' => env('DB_USERNAME', 'forge'), 'password' => env('DB_PASSWORD', ''), 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci', 'prefix' => '', 'strict' => false, 'engine' => null, ],
